Mail without authentication

[ToeiRei]

Hi there,

I am running an internal mail server here for servers that just send logs and notifications. Would it be possible to just have something like MAIL_SMTP_AUTH to none to just send it out?

Hi 👋
Do you try to just leave empty MAIL_SMTP_LOGIN and MAIL_SMTP_PWD ?

[ToeiRei]

I did not set it and the log just complains about missing login/pwd

I'm going to set up a local mail server to make this possible. It doesn't have to be very complex.

[ToeiRei]

I suspect you're using Nodemailer and therefor could use something like a custom auth that doesn't send user authentication details?

[Ravinou]

Yes, it's nodemailer.

I'd also be interested in this functionality. google smtp-relay allows to whitelist IP addresses that can send mail, and thus we don't really require authentication to send notifications and alerts from a multitude of different services.

[Ravinou]

Please, tell me if v2.4.3 solve your problem. Thank you

[ToeiRei]

We're still at An error occurred while sending the email: Error: Missing credentials for "PLAIN"

Yesterday, I mount a docker-mailserver and I everything works without login/pass. So I guess the context is different. Could you help me to be in the same context as you? Which provider or smtp do you use to do this? Google smtp relay obviously requires a business account, I don't have that...

[ToeiRei]

I use a local postfix server with no authentication for local networks. (Sorry for the delay - moving to a new place)

btw - I cannot add empty variables on TrueNAS Scale.
